JULIUS ROEVER, OF NEW YORK, N. Y.

RECORD-HOLDER.

' Application filed July 22, 1910, Serial No. 573,157.

To all whom it may concern Be it known that I,JULIUs Ronvnn, of the cityof New York, county of Queens, and

State of New York, have invented a new and useful Improvement inRecord-Holders, of which the following is a full, clear, and exactdescription.

My invention relates 'to improvements in record holders for phonographrecords and especially to that class of holders WhlCll are mounted on awheel or other rotary device, so that the records can behrought intosucccssive Operation. In record holders of thiskind it ha's been founddifiicult to get a at the sametime structure which would permit of arecord being easily Slipped on or off the holder, and permit of therecord bemg easily adjusted so that the needle of the reproducer' willstrike exactly in the right point of the record.

I The object of my invention is toproduce a record holder which willpermita record to be instantly slipped on endwise over the holderWithout the necessity of operating or adjusting any mechanism, and inwhich the.

record can then be accurately adjusted in of the reproducer.'*

A further object of my inventionis to produce a holder which is cheap tomanufacture and simple. in constru'ction,,and one in which the frictionof rotation is reduced to a minimum.

Other objects of my invention are to produce a record holder upon whicha record can be easily placed or removed, and on which the ends of therecord are left entirely free so that there is, no danger of breakingthem, and nothing to interfere with their adjustment, and further toproduce a record holder vvhichcan not only be adjusted in and out on itssupports, but has a central driving spindle extending through thesupport, and which can be entirely removed when necessary.

Another important feature of the inven tion is this: Pu vv.ographrecords are of two general kinds, known in the trade as wax records andindestructible records. The indestructible records can be carried on askeleton holder, but the wax records cannot. l'iccause they are likelyto collapse. Moreover, on record holders having a solid face, the waxrecords in either ve"y warm or very cold weather are likely to stick soSnecification of Letters Patent.

that they break in taking them 011'. I provide my record holder,however, with longitudinal corrugations so that it presents a goodgripping surface the cylinder, but will not stick closely to the waxrecord, and so such records can be easily placed on or taken oil therecord holder, while the holder is also as well adapted to securing aso-called'indestructible record.

Reference is to be had to the accompany ing drawings forming a part ofthis specification, in which similar reference characters indicatecorresponding parts in all the views. Figure 1 is a longitudinal sectionof a record holder embodying my invention, and Fig. 2 is an end view ofthe holder proper.

Themcans for carrying the record holder is immaterial and forms no partof this in vention. I have, however, illustrated it as mounted on ahorizontal disk 10. The record, holder is supported by the post 11 whichmay be secured to the disk 10 or integral therewith. This post 11terminates at its upper end in a horizontal casing 12. The record holder13 is supported by the shaft or spindle 14 which is preferably integraltherewith, and which "extends through the sleeve 15, which sleeve issupported within the casing 12. The sleeve '15 is screw threaded at eachend to receive the collars 1G and 17. These collars are beveled at theirinner ends and when screwed onto the ends of the sleeve 15, form conesfor ball bearings. Bearing cups l8 and 18 are supported rigidly withinthe casing 12 and are adapted not to contact with the sleeve 15, thesecups 18 and 18" togeher with the cones 16 and 17, forming hearings forthe balls 19.

The record holder proper 13 is in the form of a shell slightly larger incircumfercnce at its inner end, and has its outer surface longitudinallycorrugated as shown at 13 in Fig. '2, and is adapted to fit snuglyagainst the inner surface of a phonographic record. The shell 13 isclosed at its outer end, and has for convenience a handle 20 by whichtheholder 13 and the shaft 14 may be adjusted longitudinally in relationto the sleeve 15. The shaft 14 is movablev longitudinally through thesleeve 15, but is turnable therewith, and to this end I proto the innerWall of vide a keyway 21 in the sleeve 15 and a key 21 upon the shaft14. The collar 17 is elongated at its outer end forming a sleeve 22 uponwhich is mounted the friction disk 23 which is supported rigidly uponthe sleeve 22 against the shoulder of the collar 17. The friction disk23 may be rotated in any desired way. I have not shown means forrotating it, as such means form no part of the present invention. It isapparent, therefore, that when the friction disk 23 is rotated, thecollar 17 together with the sleeve 15 and the shaft 14 will rr iate withit within the casing 12 on the ball bearings provided therein. I thusprovide a record holder which will rotate With a minimum of friction andalso very smoothly and accurately, and on Whichthe record may beadjusted very nicely in relation to the stylus of the reproducer.

It will be seen that one can grasp the handle 20 and not only adjust therecord in and out on its support, but can pull the spindle or shaft 14entirely out if desired, and if necessary to do any work on the recordor other parts. This is often a great advantage.

I claim 2-- 1. A record holder comprising a horizontally arrangedcylindrical casing, a sleeve held to rotate in the casing, a collar onthe sleeve projecting from the end of the casing and carrying drivingmeans, and a shell or mandrel open at its inner end and closed at itsouter end, said shell or mandrel having a rigid internal spindle slidingfreely in and removable from the aforesaid sleeve, but arranged to turnwith the sleeve.

2. A record holder comprising a horizontally arranged casing, a sleeveturning in suitable bearings within the casing, meam for driving thesleeve, and a shell or mandrel adapted to support a record, said shellor mandrel being open at one end, closed at the other, provided with ahandle at its closed end, and having a rigid spindle arrangedlongitudinally Within it, said spindle being freely movable in theaforesaid sleeve and detachable therefrom, and also arranged to turnwith the sleeve.
